Lets say I was hired to do about 20 small jobs in another state .My pay was based on a per job basis .When i start the project it turns out the none of these jobs were surveyed properly so i end up having to drive to these jobs and more only to find out that the entire week was a waste. As a contractor am i able to charge for showing up to every site and for the time traveling from site to site ?
This would depend entirely on your contract. Presumably your contract calls for specific acts or activities. If you are requested to go above and beyond that, you would expect to get paid extra. That being said, there may have been an obligation to raise that issue much earlier than now in order to get paid extra, and your failure to raise it earlier may constitute a waiver of any entitlement to additional money. The contract is definitely the key.
